iOS - 界面偏移、状态栏导航栏显示隐藏

   self.automaticallyAdjustsScrollViewInsets = NO;

    [IQKeyboardManager sharedManager].enableAutoToolbar = NO;
    [IQKeyboardManager sharedManager].enable = NO;

状态栏颜色设置

    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;


    if (@available(iOS 13.0, *)) {
       [UIApplication sharedApplication].statusBarStyle =  UIStatusBarStyleDarkContent;
    } else {
        [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleDefault;;
    }

    if (@available(iOS 11.0, *)) {
        self.tableV.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
    } else {
        self.automaticallyAdjustsScrollViewInsets = NO;
    }

   self.tableV.estimatedRowHeight = 0;
   self.tableV.estimatedSectionHeaderHeight = 0;
   //适配ios11自适应上导航 安全区域
   self.tableV.separatorStyle = UITableViewCellSeparatorStyleNone;
   SEL selector = NSSelectorFromString(@"setContentInsetAdjustmentBehavior:");
   if ([self respondsToSelector:selector]) {
       IMP imp = [self methodForSelector:selector];
       void (*func)(id, SEL, NSInteger) = (void *)imp;
       func(self, selector, 2);

   }
